Application of integrated positive pressure needle-free indwelling needle in intravenous therapy of drug dddicts

目的探讨一体化正压无针连接式留置针在吸毒患者静脉治疗中的应用。方法选取2018年1月—2019年12月中南大学湘雅医学院附属海口医院收治的150例吸毒患者为研究对象,按照随机数字表法分为观察组(50例)、对照组1(50例)、与对照组2(50例)。观察组采用一体化正压无针连接式留置针输液;对照组1用24G密闭式留置针连接肝素帽输液;对照组2用密闭式留置针连接分隔膜无针接头输液。比较三组的留置时间和留置期并发症(堵管、针刺伤、导管内回血、静脉炎、外渗、穿刺点渗血)。结果观察组、对照组1和对照组2的留置针的留置时间分别为(4.89±0.21)d、(3.32±0.28)d、(3.87±0.28)d,与对照组1和对照组2比较,观察组的留置针留置时间长,差异有统计学意义(P<0.05)。观察组、对照组1和对照组2留置针留置期的堵管、针刺伤、导管内回血的占比分别为4%、0%、10%;28%、16%、72%;28%、16%、72%,观察组的堵管、针刺伤、导管内回血的发生率低于对照组1和对照组2,差异均有统计学意义(P<0.05)。观察组、对照组1与对照组2留置针留置期间的静脉炎、外渗、穿刺点渗血的占比分别为16%、6%、8%;12%、12%、16%;12%、12%、16%,观察组的静脉炎、外渗、穿刺点渗血与对照组1和对照组2比较,差异无统计学意义(P>0.05)。结论一体化正压无针连接式留置针留置针可以预防堵管,延长导管留置时间,减少反复穿刺和穿刺次数对血管的损伤,保护患者血管,降低静脉炎发生。

Objective To explore the application of integrated positive pressure needle-free indwelling needle in intravenous therapy of drug addicts.Methods A total of 150 drug addicts admitted to Affiliated Haikou Hospital of Xiangya Medical College,Central South University from January 2018 to December 2019 were selected as the research objects and divided into the observation group(50 cases),and the control group 1(50 cases),and control group 2(50 cases)according to the random number table method.The observation group:was integrated positive pressure needle-free indwenting-needle infusion;control group 1 was used 24 G closed indwerable needle connected with heparin cap infusion;control group 2 was used closed indwelling needle connection separator diaphragm without needle joint infusion.The duration of indwelling and complications during indwelling were compared among the three groups(blocked tube,needle puncture wound,intraductal blood loss,phlebitis,extravasation,and extravasation at puncture point).Results The indwelling time of the needle in the observation group,the control group 1 and the control group 2 were(4.89±0.21)d,(3.32±0.28)d and(3.87±0.28)d respectively,which was longer than that in the control group 1 and the control group 2,the differences were statistically significant(P<0.05).The proportion of cases in the observation group,the control group 1 and the control group 2 during the indwelling of the indwelling needle were 4%,0%,10%;28%,16%,72%;28%,16%,72%respectively.The incidence of blocked tubes,needle stick injuries,and intrathecal blood recovery in the observation group were lower than that in the control group 1 and 2,with statistical differences(P<0.05).The propotion of the cases of phlebitis,extravasation and blood extravasation at the puncture point during indwelling needle in the observation group,the control group 1 and the control group 2 were 16%,6%,8%;12%,12%,16%;12%,12%,16%respectively,the phlebitis,extravasation,and extravasation at puncture point in the observation group were compared with those in control group 1 and control group 2 showing no statistically significant differences(P>0.05).Conclusion Integrated positive pressure needle-free indwelling needle indwelling needle can prevent tube plugging,prolong catheter indwelling time,reduce vascular damage caused by repeated puncture and puncture times,protect blood vessels of patients,and reduce the occurrence of phlebitis.
